Application June 25, 1932, Serial No. 619,195 Renewed March`25, 1935 Claims.

va looped body strap is secured at its ends to a single reciprocating armature actuated by electromagnetic means, and in which the opposite ends of lthe straps are converted to hooks that are in turn connected to the armature through a centrai connecting link;

Second, to "provide a vibrator of this class in which the armature is slidably mounted on leaf springs;

Third, to provide a vibrator of this. class in which the amature is held in position by means of leaf springs;

Fourth, to provide a vibrator of this class in which the motion of the armature toward the magnet is restricted;

Fifth, to provide a vibrator of this class that has ample strength for any occassion;

Sixth, to provide a'vibrator of this class which is extremely compact of construction, one which may readily be transported from place to place, and one which may be readily supported for operative use; and

Seventh, to provide a vibrator of this class which is particularly simple and economical of construction and operation and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanyingdrawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a top view of my body vibrator showing certain parts and portions thereof broken away and in section to facilitate the illustration; Fig. 2 is a side view thereof with the cover shown in section and certain parts and portions broken away; Fig. 3 is a front view thereof with certain parts and portions broken away as indicated by the line 3--3 of Fig. 1; Fig. 4 is a transverse sectional view thereof taken through 4-4 of Fig. 1; Fig. 5 is a fragmentary top sectional view taken through 5-5 of Fig. 2, showing only the front portion thereof; Fig. 6 is a fragmentary top sectional view of my body vibrator with a somewhat (Cl. 12S-63) 'different arrangement of parts, the section "being taken similar to that of Fig. 5.

Like-characters of reference refer to similar parts and `portions throughout the several views of the drawings.

The' operating portions of my device consists of an electro-magnet A and an armature B. These are enclosed in a casing I having removable end s Iw and Ib. The casing I consists of two semi-cylindrical portions which are connected together by means ofthe screen Ic, the screen serving as a Ventilating means.

The electro-magnet A consists of a winding 2 and the double horse shoe type core 3, the core 3 being mounted at one end of the supports 4 and` lo 5. The supports 4 and 5 at the end where thev core of the electro-magnet is mounted are narrow and contain slots 4a and 5a for securing the strap S. The other ends of the supports 4 and 5 are wide and are bent over in a U-shape, forming arms 4b, 4c, 5b, and 5c. Extending beyond the position of the arms the supports are provided with strong elongated semi-cylindrical portions 4d and 5d. These portions are provided with slots 4e and 5e for engaging and holding the ends of leaf springs 6 and 1. The ends of the arms 4b, 4c, 5b, and k5c are provided with cushions 8` and serve to restrict the motion of the springs 6 and 1 toward the electro-magnet A. The supports 4 and 5 are provided withlugs 4f, 4g, 5f, and 5y, these lugs being drilled and tapped and serving to secure the ends Im and Ib of the casing I in place.

The armature B consists of a multiplicity of sheets of metal designated 9, and a heavy flat piece oi metal designated I0. The heavy flat piece of metal I0 is of a width at one end equal to the length of the laminations 9 and then tapers down to form a connecting link II and is then shaped at the other end into the bar I2 that contains the hooks I3 and I4. The connecting link II is provided with bracket arms I5, these arms serving as a means for securing the armature and hooks to the springs 6 and 'I. With this arrangement of parts the armature B is held in a fixed relation with the electro-magnet A.

The hooks I3 and I4 are used in securing the ends of the body strap I6 of which a portion is shown in Figs. 1 and 2. When a force is exerted on the body strap I6, this force is in turn exerted on the leaf springs 6 and 'I which causes them to be deflected and at the same time causes the entire armature to be moved away from the electromagnet A, as shown by dotted lines in Fig. 5, thus when the electric current is turned on the armature will be free to vibrate within the limits of the action of the springs.

Figure 6 shows my body vibrator with a slight modification in the arrangement of the armature and leaf springs. 'I'he armature is mounted on the leaf springs 6 and 'I as in the previous arrangement, but spaced a short distance from the springs 6 and I are mounted a second set of springs designated I1. 'I'his set of springs is mounted inV slots 4h and 5h as are the springs 6 and 1. 'Ihe side of the bracketv l'toward the second set of springs I1 is fitted with a rubber cushion I8. The springs I'I do not function until the force applied to the hooks I3 and I4 is greatenough to deflect the springs 6 and I far enough to permit the rubber bumper I8 to engage with springs II. Therefore the principal function of springs I1 are to relieve the strain on springs 6 and 'I when these springs have been deflected beyond a certain position.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, and a certain modification thereof, I do not Wish to be limited to this particular construction, combination and arrangement nor to the modification thereof, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appendedclaims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a body vibrator, a frame, an electro-magnet mounted at one end thereof, a laminated leaf g spring mounted at the opposite end thereof and supported at its ends on said frame, an armature operatively mounted on said spring and positioned between said electro-magnet and said spring, a support for said armature secured to said spring and extending past said frame and provided with a bifurcated end, and a strap secured to the bifurcated end of said support.

2. In a body vibrator, a frame, an electro-magnet mounted at one end thereof, a pair of leaf f springs mounted at the opposite end thereof, an

armature supported by one of said springs positioned between said electro-magnet and said spring in operative relation to the electromagnet, and a connecting means connected to said armature and extending past the opposite side of both of said springs, said connecting means provided with means for engagement with one of said springs to restrict the movement of the other spring.

3. In a body vibrator, a frame, an electromagnet mounted at one end thereof, a first leaf spring mounted at the opposite end thereof, a second leaf spring mounted at' the opposite end thereof 10 in spaced relation to said first leaf spring, an armature interposed between said first leaf spring and said electro-magnet, and a supporting means secured to said first leaf spring and supporting said armature in operative relation with said electro-magnet and provided with a cushion member adapted to engage said second leaf spring for retarding the movement of said rst leaf spring.

4. In a body vibrator, a frame, an electro-magnet mounted at one end thereof, a laminated leaf spring mounted at the opposite end thereof and supported at its ends on said frame, an armature operatively mounted on said spring and positioned between said electro-magnet and said spring, a support for said armature secured to said spring and extending past said frame and provided with a bifurcated end, a strap secured tothe bifurcated end of said support, a strap secured to the opposite end of said frame from said first mentioned strap, and a casing engaging said frame.

5. In a body vibrator, a frame, an electro-magnet mounted at one end thereof, a laminated leaf spring mounted at the opposite end thereof and supported at its ends on said frame, an armature operatively mounted on said spring` and positioned between said electro-magnetV and said springa support for -said armature secured to said spring and extending past said frame and 40, provided with a bifurcated end, a strap secured to the bifurcated end of said support, a strap secured to the opposite end of said frame from said rst mentioned strap, and a casing engaging said frame, said casing provided with a foraminous L5 portion for Ventilating purposes.
